ECOMMENDED
This manual outlines two specific types of enclosures that provide distinctly different performance.This
section is to help you decide which type is best for your application.
SEALED ENCLOSURES
Sealed enclosures are the simplest to build.The most important part of building a sealed enclosure is to
make sure that the enclosure is airtight. Using glue and some type of sealant on all seams will ensure solid
construction and prevent air leaks.The box volume will directly impact the performance of the speaker.
Larger enclosures will provide flatter response and deeper bass where smaller boxes will provide a bump
in the response curve and generally higher output for greater SPL.
Advantages of sealed enclosures:
• Small enclosures
• Linear (Flat) response
• No port noise
